The width of a rectangle is 5 units less than the length. The area of the rectangle is 6 units. What is the width, in units, of

Readme [11.4K]

Answer:

The width of rectangle is 1 unit.

Step-by-step explanation:

Given:

The area of rectangle is 6 units and its width is 5 units less than the length.

So, to find the width of rectangle.

Let the length be $x$ and the width be $x-5$ .

Now, to find the width we put the formula of area of rectangle:

Area = length × width

$6= x\times (x-5)$

$6=x^{2}-5x$

$0=x^{2}-5x-6$

$0=x^{2}-6x+x-6$

$0=x(x-6)+1(x-6)$

$0=(x-6)(x+1)$

<em>On solving equation we get:</em>

$x-6=0, x+1=0$

Therefore, we take the value x=6 as it is positive value:

$x-6=0$

$x=6$

So, the width of rectangle:

Width = $x-5$

= $6-5$

= $1$

Therefore, the width of rectangle is 1 unit.

Find the measure of the each angle indicated. HELP

Paraphin [41]

Answer:

(n-2)180 (this is the equation to find the sum of interior angles)

(4-2) 180 (plug in the amount of angles in the polygon and then solve)

2* 180

360

360 - 115 -100- 73= 72 (360 is the sum of all angles for this polygon. so subtract the known angles to find the unknown one)

measure of angle B is 72 degrees
